X-Message-Number: 4415 From: Date: Thu, 18 May 1995 18:33:41 -0400 Subject: misc. Eugen Leitl, in one of his interesting postings (#4409), says a couple of things with which I would take mild issue. 1. He suggests (as many others have done) that long-livers might be extremely risk-averse, staying home to avoid accidents etc and thus subject to boredom. There are several things to be said here: First, the risk of death per person per year will not be a constant and will (probably) not be anywhere near today's value. The improvement in repair capability and in safety mechanisms will reduce the risk number; and the prospect of long life will reduce the number of desperate or menacing people. Second, the need or desire to travel or to mingle may diminish, as individuals become effectively wealthier and as virtual reality type devices allow simulated travel to become more and more realistic. Telephones have for many years allowed us to talk to friends without visiting them; vidphones are beginning to allow sight as well; this trend will continue. Mr. Leitl also indicates that (at least some) uploading issues have been long settled. Unless he was being ironic, this is wrong. The central issue of criteria of survival is nowhere near settled. In particular, two unresolved issues are outstanding: 1. We do not know the anatomy/physiology of the subjective circuit or the self circuit--the seat of feeling and the ground of being--hence cannot say whether it is supportable outside of organic brains. 2. We have not resolved the "philosophical" isues related to duplication and to continuity. 3. We know almost nothing about time (or spacetime), and cannot even say for sure that we "survive" (in some appropriate sense) in the ordinary course of events. Is any of this useful? Aside from the amusement value, it may conceivably add a trifle to the incentive for cryostasis, to allow future pursuit of these matters.
